Antifouling and antibacterial porcelain glaze and preparation process thereof
The invention relates to the technical field of glazes, and discloses an antifouling and antibacterial porcelain glaze and a preparation process thereof.The preparation process includes: subjecting diethyl iminodiacetate and Br (CH2) nBr to catalysis of triethylamine and hydrolysis reaction of hydrochloric acid to obtain a polycarboxyl surfactant, dissolving the polycarboxyl surfactant, zinc chloride and polyethylene glycol in a sodium hydroxide solution, and stirring to obtain a mixture; the preparation method comprises the following steps: carrying out a constant-temperature water bath reaction to obtain flower-cluster-shaped nano ZnO, carrying out ultrasonic dispersion on the flower-cluster-shaped nano ZnO, adding nano silver into the flower-cluster-shaped nano ZnO, carrying out magnetic stirring to obtain nano silver-loaded flower-cluster-shaped nano ZnO, uniformly mixing dried glaze, nano silver-loaded flower-cluster-shaped nano ZnO, a polycarboxylic surfactant and a thicker material of sodium methyl cellulose, dissolving the mixture in a phosphoric acid aqueous solution, and carrying out ball milling and drying to obtain the nano silver-loaded flower-cluster-shaped nano ZnO composite material. The antifouling and antibacterial glaze is obtained. The anti-fouling and anti-bacterial porcelain product glaze is applied to a blank body to obtain the anti-fouling and anti-bacterial porcelain product, the growth of crystals can be inhibited, and the formation of metal cations or crystal molecular clusters can be prevented, so that the effects of scale inhibition and fouling prevention are achieved, and the anti-bacterial effect of the porcelain product is improved.
本发明涉及釉料技术领域，且公开了一种防污抗菌的瓷制品釉料及其制备工艺，亚氨基二乙酸二乙酯、Br(CH2)nBr在三乙胺的催化以及盐酸的水解反应条件下得到多羧基表面活性剂再将其与氯化锌、聚乙二醇溶于氢氧化钠溶液，恒温水浴反应得到花簇状纳米ZnO，将花簇状纳米ZnO进行超声分散，再向其中加入纳米银磁力搅拌，得到纳米银负载花簇状纳米ZnO，将干燥的釉料、纳米银负载花簇状纳米ZnO、多羧基表面活性剂、甲基纤维素钠更稠料混合均匀，溶于磷酸水溶液中，球磨、干燥，得到防污抗菌釉料。将防污抗菌的瓷制品釉料应用于胚体上而得到抗菌防污瓷制品，能够抑制晶体的生长，阻止金属阳离子或结晶分子簇的形成，从而达到阻垢、防污的作用，提高了瓷制品的抗菌效果。
